Application filed April 22, 1915. Serial No. 23,170.

To this end, the great desideratum, of

course, is simplicity and consequent cheapness of construction, so that the graphophone-toy may not be of prohibitive cost, butmay be manufactured at a low figure and sold at anominal sum, at a substantial profit.

At the same time, the object is, with cheapness of construction, to provide a structure which shall present all reasonable ear of the auditor, and in which the shall be clear and distinct.

durability. Additionally, it is an object to provide a .graphophone-toy, for use with disk records,

which will, in operation, be musical to the tone A further object is to provide a graphophone in which all noise, such. as rattling or clicking of machinery, shall be eliminated, thereby insuring .a more satisfactory playing of the records.

e A further object is to eliminate the use of the spring motor, which characterizes the customary graphophone' now on the market;

A spring motor is always getting out of order, after a period of use thereof, and

needs cleaning, etc.-,-, to maintain the same in propercondition, and, besides, the spring motor makes more or less noise operation. It is, therefore, the object of my invention to substitutemeans whereby thedisk-supporting table may be manually revolved, with a minimum of effort and a maximum of ease.

Other objects relate to details and refinements of construction, going to. make up With these objects in view, theinvention resides in the novel construction; combination and arrangement of-parts ofa toy-graphophone, such as hereinafter fully described 2-111 the specification, summed up in the claims, and illustrated inthe-drawings. i

In the accompanying drawings, I have shown diflerentillustratory ways of'carrylng out the underlyingprinciples of theinvention; it being understood that'like referslice-characters denote corresponding parts throughout the several views. T

The difierent views of the drawingsmayt be briefly described as follows: Flgure 1 1s a side elevation ofthepreierred form of my invention Fig. 2 is a vertical sectional view'on the line 2--2, Fig. 3.

My invention relates to that class of talking-machines in which the reproduction of- I i sound is effected-without a diaphragm, 'by thevibration of a trumpet or horn by a stylus operatingupon therecordwhich car-- ries thesound-writing. Referring, now, in detail. to the drawings,

. and, first, to. Figs. 1* to 10 thereof 2.1 ,desig:

nates a base, which, for purpose of simpli'city andfconvenience to manufacture, is

of sheet metal, as shown, stamped and pressed up. into the desired form. The hase comprises, preferably, a fiatplate provided -with a marginal,- dependingfiange 2 entirely surrounding the plate. In this base 1, desirably formed integral therewith, is a pocket 3, there being, if desired, more than one of such pockets, for the reception, respectively, of unused and used reproducerneedles. The sheet-metal base 1 is also desirably provided with preferably integral lugs 4, for a purpose presently appearing, and which are desirably formed by slitting or cutting the material of the base and bending up the material along the lines of the cut, openings 5 being thus left in the base.-

6 designates a preferably sheet-metal casing, which may be of any desired form, and is seated upon the base 1 and secured thereto, preferably in the manner and by the means now to be described. The shell or casing 6 is providedwith openings 7.

WVhen the shell 6 is placed on. the base, in assembling'the parts, the bent terminals 4 (see Fig.4) of the lugs==. 4 are sprung through the openings 7, and said terminals then bent down (as shown in Fig, 2), so asto bear against the outer surface of the shell or" casing 6 (as shown in 1g. 2), thereby securing said shell in position on the sheet-- metal base 1, against accidentalxdisplaca ment or removal therefrom.

Carried by the base 1, interiorly of the casing 6, are two, spaced, preferably wooden blocks, 8, 9, which may be conveniently secured to the base by screws 10. Carried by the block 8, preferably on one side thereof, is a preferably metallic bracket 11, COIL" veniently secured to said block by screws 12.

' The bracket is apertured, as shown, and said apertures constitute bearings for the revoluble spindle 13 axially carried by the rotatable table 14, and pinned thereto, as shown at 15. The table 14 preferably carries, on its under surface, axially thereofja preferably paper disk-washer 16, which may be pasted to the table 14.

supported by said'tube is a rod 23, having an angularly-bent portlon 24, having, at its free end, a right-angularly bent hook 25, which, in practic ,,engages an eye or ring 26, preferably of rubber, carried by a horn 27, preferably through the medium of a strip of suitable material 28, preferably fabric, suitably secured, as by paste, or stitching, or rivets. or the 11ke, to-the horn, which latter, from the stand-point of cheapness to therein, whereb The table also preferably carries,ion its top, the usual felt manufacture, is preferablymadeof paper, suitably treated, as by varnish, orthe like, to makeit stiff and reasonably durable. It, is to be understood, however, that the horn may be formed of. any other sonorous ma-. terial. The horn carries, projecting therefrom at its reduced extremity, a plug, 29, preferably of rubber, provided with a vertically inclined-opening therethrough, through which a, reproducer-needle 30 may be assed and, held therein by friction.

he stylus or reproducer needle 30 carries, at its upper end, a removable weight 31, which I have found, b. experiment, to be very desirable and, in act, essential to the proper operation of the graphophone. Said weight 31 is, desirably, a metallic disk, and, as shown in Figi 5, it is provided with a recess 32 in which is seated an inset 33, of elasf ticmaterial, such as rubber. This inset 33 has a longitudinally-extending recess 34 the weight may be seated on and carried by the top of the needle.

'Encircling the reduced end of the horn isa reinforcing-thimble 35, of suitable mate rial,.prefer'ably fabric, which maybe pasted to said reduced end of the horn.

As shown in Fig. 6,;a friction clamp 36 may encircle the reduced end of the; horn and the fabric thimble 35 carried thereby, said clamp being tightened by means of a screw 37 As shown in Fig. 13, the horn 27 fmay carry, in its reduced end, a rubber disk 38 eccentrically carrying an integral cylindrical projection 39, through which the reproducer- I needle 30 passes, and is frictionally held therein.

Fig. 14 merely shows a metallic diskweight 31 provided with a rubber inset 33 disposedin one face thereof, instead of in the perimeter of the disk, as shown in Figs.

'5 and 7. I

In Fig. 16, 39 designates a metallic or wooden plug seated in the reduced end of the horn 27 39 is a rubber gasket or thimble encircling the plug 39*. The. reproducerneedle 30 projects through an inclined aperture in said plug, andlis clamped therein by means of a set-screw 39.

Referring, now, to Figs. 11 and 12: Here, the base 1 is a wooden,'-instead of a metallic, plate; and carries a cylindrical casing 6*. Interiorly of the casing, the base carries a preferably metallic bracket 40, comprising the base portion, as shown, from which rise standards 41,42, 42, the standard41 forming bearings for the rotatable spindle 13 of the rotating table 14, and the standards 42, 42

forming bearings for the crank-shaft 19 carrying at its innerend the friction disk 20*. F lg. 12 merely shows a different form of bracket 40, which may be substituted for the bracket .40, of Fig. 11. In the bracket 40*, one of the standards 42 is formed by ber plug carried by and projecting from said I the provisions of the-patent. statutes,

with great particularity described certaln.

slitting the metal of the bracket and bending it up, as shown, leaving a slot 40?. While, for. the purpose of complyinglwith ave instrumentalities for carrying into effectthe underlying principles of-the invention, it is to be understood that all modifications of structure as come within the scope of thea'ppended "claims constitute no departure from the spirit of the invention,- and fall strictly Within the scope and purview thereof.

Having thus fully described my invention,
